Alexander Boettcher 5e5fe7291a nic/ipxe: add throttle RX interrupt support ... The commit adds support to throttle the rate of the RX IRQs to a specified value. The effect is, that no RX IRQs below the time threshold will fire and therefore the CPU load gets reduced on the host. Trade-off gaming between cpu load, throughput, overload. Modular Sculpt 23.10 on S938 as testcase. In brackets the CPU affinity is denoted. ipxe (0,0) -> nic_router (1,0) -> Debian VM vbox6 (3,0) and (3,1) VM: iperf -C X.X.X.X -t 60 -R iperf server X.X.X.X is outside Sculpt and sends data due to '-R' to VM Non representative measure points: cpu load - ipxe - nic_router - iperf throughput -------------------------------------------------- w/o patch - ~80% - ~50% - ~706 MBit/s - 0 -> throttling off by default on S938 patch 651 - ~20% - ~35% - ~763 MBit/s - 651 -> 0.166ms throttle RX IRQ patch 5580 - ~15% - ~25% - ~650 MBit/s - 5580 -> 1.4ms throttle RX IRQ Issue #5149		2024-04-12 15:00:44 +02:00
